摘　　要：针对水力机械磨蚀问题,从冲刷、空蚀等角度研究了磨蚀机理,并在此基础上总结各电站多年抗磨蚀经验,提出合理布置水利枢纽、优化机组配置和运行参数、采用新材料及工艺等方法,分析了各种抗磨蚀技术的优劣,并对抗磨蚀技术中的新材料、新工艺等方法展开深入分析,探讨了金属堆焊、非金属涂层、合金粉末喷焊和高速火焰喷涂等技术,进而对今后水力机械抗磨损的研究发展进行了展望,即采用新材料、新工艺是水力机械抗磨蚀的主要发展方向。According to the abrasion of hydraulic machinery,the abrasion mechanism is studied by the views of erosion and cavitation.Based on the summarizing the anti-abrasion experience of power stations,the measures,namely reasonable layout of water conservancy,optimizing the unit configuration and operating parameters,using new materials and processing methods,are used to anti abrasion,and analyzes the various anti abrasion technology advantage.And then the new technology of abrasion technique are discussed,such as the metal surfacing,non-metallic coating,alloy powder spray welding and high speed flame spraying technology.At the end,the forecast to the research and development of anti-wear hydraulic machinery are carried on,and using new materials,new technology are the main direction of development for anti-abrasion of hydraulic machinery.
